OBJECTIVETo explore the prevalence of IDH gene (IDH1 and IDH2) mutations, types of mutations in patients with acute myeloid leukemia (AML), correlation with the internal tandem duplication(ITD) mutation of FLT3 gene, NPM1 gene mutation and some clinical characteristics.

METHODSThe mutations of IDH1 and IDH2 gene at exon 4, NPM1 gene at exon 12 and FLT3-ITD at exon 14 and 15 in 163 newly diagnosed AML patients were detected by PCR amplification followed by direct sequencing of genomic DNA.

RESULTS(1) IDH mutations were found in 25 patients (25/163), and all were heterozygous, of which IDH1 in 7 patients (4.29%) and IDH2 in 18 (11.04%). A total of 4 types of IDH1 mutations were identified (c.395G→A, p.R132H, n = 4; c.394C→A, p.R132S, n = 1; c.394C→G, p.R132G, n = 1; c.315C→T, n = 1). The IDH1 mutation caused substitutions of residue R132 except for one (c.315C→T). All IDH2 mutations caused changes of R140 (c.419G→A, p.R140Q, n = 18). The incidence of IDH2 mutation was significantly higher than that of IDH1 mutation (11.0% v 4.3%, P = 0.022). Both IDH1 and IDH2 mutation were detected in one patient, while IDH1 was synonymous substitution (c.315C→T). IDH-mutated cases showed a significantly higher frequency of concurrent FLT3-ITD mutation compared with wildtype cases (34.6% vs 11.9%, P = 0.003), so did IDH mutations concurrent NPM1 mutation vs NPM1 wildtype (28.1% vs 12.7%, P = 0.033), of which the frequency of concurrent NPM1 and FLT-ITD mutations cases with the IDH mutation was significantly higher than that of NPM1 and FLT-ITD negative (45.5% vs 11.7%, P = 0.002). IDH mutation incidence was significantly higher in normal karyotype cases than in abnormal ones (20.5% vs 5.8%, P = 0.020). Patients with IDH mutations were significantly older than wildtype patients(P < 0.001), whereas, there were no statistically significant differences in gender, peripheral blood (PB) count at diagnosis between two groups.

CONCLUSIONSThe incidence of IDH mutation is higher in patients with de novo AMLs, of which IDH2 mutation more frequently, and the patients associated with older age, normal karyotype at diagnosis. IDH mutation has a strong association with NPM1 and FLT3-ITD mutations, suggesting that IDH mutation has synergistic effect with the latter gene on leukemogenesis.

OBJECTIVETo explore the therapeutic feasibility of allogeneic hematopoietic stem cell transplantation (allo-HSCT) from partially HLA-mismatched related donors for hematologic diseases.

METHODSThirty patients with hematologic diseases received allo-HSCT from 1 - 3 loci mismatched related donors conditioning regimen consisting of ATG (thymoglobulin, total dose of 10 mg/kg, intravenously on - 4 d to - 1 d), and only 5 (18%) of 28 recipients from HLA-identical sibling donors were treated with regimen containing ATG. Donors were given G-CSF prior to hematopoietic stem cell harvest and CsA, short-term MTX and mycophenolate mofetil (MMF) were used for GVHD prophylaxis in both group.

RESULTSAll patients were successfully engrafted. There was no significant difference in the incidence of grade II to IV acute graft-versus-host disease (aGVHD) and grade III to IV aGVHD between the mismatched and matched groups (34% vs 32%, and 13% vs 11%, respectively). 3-year overall survival (OS) and disease-free survival (DFS) in mismatched and matched groups were 57% vs 77% (P = 0.14) and 57% vs 69% (P = 0.28), respectively. Multivariate analysis showed that advanced disease pre-transplant (P = 0.006) and CMV infection (P = 0.04) were risk factors for OS. OS for patients with stable disease in mismatched and matched groups were 87% vs 81% (P = 0.65) respectively, and for those with advanced disease were 21% vs 71% (P = 0.02).

CONCLUSIONSIt is feasible to perform allo-HSCT from 1 -3 loci HLA-mismatched related donors for patients with stable disease who lack HLA-identical sibling donors. Nevertheless, for patients with advanced disease optimized conditioning regimen and intensive supporting therapy should be administered to obtain better clinical outcomes.

OBJECTIVETo provide the evidence of RQ-PCR-based assessment of minimal residual disease (MRD), the clonal immunoglobulin and T-cell receptor (Ig/TCR) gene rearrangements were identified in newly diagnosed adult patients with acute lymphoblastic leukemia (ALL) by multiplex PCR protocols.

METHODSForty newly diagnosed adult patients with B-lineage (B-) and T cell (T-) ALL were involved in this study. All DNA samples were obtained from the bone marrow (BM) mononuclear cells (MNC). IgH, IgK, TCRB, TCRG and TCRD gene rearrangements were detected by BIOMED-2 multiplex PCR protocols, which included 96 different primers and 14 multiplex PCR tubes.

RESULTSThe clonal immunoglobulin (Ig) rearrangements were found in 96% of B-ALL, 86% being IgH and 14% IgK. While in T-ALL, clonal TCR rearrangements were found in all of the patients, 83% being TCRB, 78% TCRG and 39% TCRD. More than two clonal markers were found in 91% of B-ALL and 89% of T-ALL patients.

CONCLUSIONSThe detection rate of clonal rearrangements using the BIOMED-2 14 multiplex PCR tubes is high, which can detect virtually all clonal B and T-cell proliferations. It can be used for diagnostic clonality studies as well as for the identification of PCR targets suitable for the detection of minimal residual disease.

This study was purposed to investigate the short-term effects of citrate administration on bone metabolism in the healthy blood donor volunteers. A crossover, placebo-controlled trial were conducted on 22 healthy blood donor volunteers. The volunteers received either a standardized infusion of citrate at 1.5 mg/(kg.min) or the equal volume of placebo normal saline, were washout for 2-3 weeks. During washout serial blood samples were collected and analyzed for bone biochemical markers and electrolytes, such as bone formation marker osteocalcin (OC), bone resorption marker carboxyterminal telopeptide of type I collagen (CTX), intact parathyroid hormone ((i)PTH), ionized calcium ((i)Ca(2+)) and phosphorus (P(i)). Serial urine samples were collected and analyzed for Ca(2+), P(i) and creatinine concentration. The results showed that compared with placebo group, infusion of citrate increased serum levels of OC and CTX (p < 0.0001). The greatest increase of OC and CTX levels occurred at the completion of the intervention. The increment of CTX was higher than OC (p = 0.02), and the OC/CTX ratio decreased (p < 0.01). Infusion of citrate also induced profound increase in serum (i)PTH level (p < 0.0001) and urinary calcium excretion (p < 0.0001), and decrease in serum (i)Ca(2+) (p < 0.0001) and P(i) (p < 0.01) levels. The decrease of (i)Ca(2+) level in female was higher than that in male (p = 0.007), but the changes of (i)PTH, OC, and CTX levels showed no differences between female and male. Changes of OC and CTX levels were closely related to each other (r = 0.56, p < 0.0001) and changes of both markers were negatively correlated with the change of serum (i)Ca(2+) concentration during the citrate intervention(r(OC) = -0.44, r(CTX) = -0.44, p < 0.0001). Increased levels of (i)PTH showed positively correlation with OC (r = 0.34, p = 0.02) and borderline correlation with CTX (r = 0.29, p = 0.06) in male. No such relationship was observed in female. All bone markers and electrolyte levels returned to baseline within 24 hours. It is concluded that the citrate load at the dose as a single platelet apheresis results in profound increase of bone turnover, which is characterized by a short-term increase of bone resorption and excretion of calcium. The possible effect of citrate on bone mass of long-term frequent platelet apheresis donor is worth concerning.

With the increasingly more serious environmental pollution in China in recent years, effective intervention with PM25-induced health risks has become a major scientific issue to be addressed urgently in medical research field in China. NOD-like receptors (NLRs) are a family of cytoplasmic pattern-recognition receptors that have critical roles in innate immunity. On the basis of study progresses in international cardiovascular disease research "Fine particulate matter exposure is a modifiable risk factor for the morbidity and mortality of cardiovascular diseases", and with reference to the current understanding of pulmonary inflammation and oxidative stress in PM2.5-induced acute coronary syndrome, this study intended to investigate whether intracellular pattern recognition NL-RP3 plays a important role in the inital event of PM2.5 induced vessel inflammation as a foreign matter in the process of plaque destabilization and to thoroughly explore the underlying mechanisms responsible for PM2.5-induced acute cardiovascular events. On the other hand, it also studies the feasibility of using traditional Chinese medicine to treat plaque destabilization cause by PM2.5 exposure and discuss it's pathogenesis and intervention strategy based on TCM theory. This paper in order to provide scientific basis for social focal issues in public health proactively and offers the references for relevant research.

Objective To understand the awareness of AIDS related knowledge, high risk behaviors, the infection status of HIV, syphilis and HSV-2, and to explore the associated factors with HSV-2 infection among whoremasters in Kaiyuan City, so as to provide scientific evidence for targeted intervention to prevent and control HIV and other STDs. Methods A self-designed questionnaire survey was conducted among whoremasters recruited through outreach activities and snowball sampling. The blood and urine were also collected for corresponding laboratory examination. Results Among the whoremasters, 98.22% had a high awareness of AIDS related knowledge, 9.33% once used drugs, and 14.67% did not use a condom during the latest commercial sex. 62.22% of the whoremasters ever had non-marital sex partners, and of those who had sex with non-marital sex partners in the past year, 59.55% reported using condoms inconsistently. The total infection rate of HIV/syphilis/HSV-2 was 18.22% and the infection rates of HIV, syphilis and HSV-2 were 3.11%, 1.33% and 16.44%, respectively. The older whoremasters were more likely to have a higher HSV-2 infection rate (AOR=1.044,95%CI:1.016-1.073,P=0.002), and those whoremasters not using a condom during the latest commercial sex were more likely to have a higher HSV-2 infection rate (AOR=3.125,95%CI:1.229-7.945,P=0.017). Conclusions Though whoremasters in Kaiyuan City had a high awareness of AIDS related knowledge, they had high-risk behaviors and relatively high HIV and other STDs infection rates. Targeted interventions are needed to improve the risk awareness of STDs infection to promote consistent condom use in both commercial and non-marital sexual behaviors among whoremasters.

The purpose of this study was to summary the clinical and laboratorial features in 15 adult cases of mixed phenotypic acute leukemia with Ph chromosome and/or BCR-ABL fusion gene positive (Ph(+)MPAL), 15 adult patients with Ph(+)MPAL were defined by WHO-2008 classification. The clinical characteristics, results of morphology, immunology, cytogenetics and molecular genetic detections and results of follow-up in 15 adult patients with Ph(+)MPAL were analyzed retrospectively. The results showed that 15 patients among 87 cases of MPAL demonstrated Ph(+)MPAL (17.2%; 15/87) (7 males and 8 females), their median age was 51 (range 16-81) year old and median WBC count at diagnosis was 69 (12.7-921)×10(9)/L. Based on FAB criteria, these patients showed different morphologic types, including AML (13.3%; 2/15), ALL (40.0%; 6/15), HAL (46.7%; 7/15). Immunologic analysis indicated that 15 cases of Ph(-)MPAL were all classified as B-lymphoid +myeloid mixed immunophenotype. Except one patient, all expressed CD34 antigen on the surface of leukemia cells with 64.3% strong positive, only Ph (53.3%; 8/15), Ph with additional chromosomal abnormalities (33.3%; 5/15) and normal karyotype (13.3%; 2/15) were cytogenetically identified. BCR-ABL fusion gene transcript positive were detected by multiplex reverse transcription PCR in all cases, with e1a2 subtype (p190) (40.0%; 6/15) and b2a2 or b3a2 (p210) subtype (60.0%; 9/15). Four out of 7 (57.1%) patients were found to have IKZF1 gene deletion, without other common gene mutations. Seven out of 10 cases (70.0%) achieved complete remission (CR) after one cycle of induction chemotherapy. In the induction stage, CR rate seemed higher when tyrosine kinase inhibitors (TKI) were added to chemotherapy (83.3%:50.0%; P = 0.206). Overall survival (OS) in 4 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) was longer than that in 4 patients received chemotherapy alone (P = 0.004). It is concluded that Ph(+)MPAL mainly is expressed as B+My phenotype. The majority of patients is older and has CD34 overexpression. In the aspect of molecular genetics, the Ph(+)MPAL is similar to other acute leukemia with Ph chromosome. Ph(+)MPAL is a subtype of acute leukemia with poor prognosis. WBC count at diagnosis is an independent prognostic factor. The combination of TKI and allo-HSCT can improve their long-term survival, which needs to be confirmed through carrying out a prospective and multicenter clinical trial for newly diagnosed Ph(+)MPAL.
